Lighting shapes how a booth or stage photographs and how a product looks under scrutiny, and rigging is what gets fixtures overhead instead of on stands cluttering the floor. The two are planned together because a lighting concept that assumes overhead truss is unusable if the venue cannot support it.
At a union convention hall, rigging above a set height is typically certified-rigger jurisdiction, separate from general exhibit labor, and it is billed and scheduled on its own timeline. A Barker Hangar or hotel booking has different structural limits and different labor rules entirely.
We pull the venue's rigging plot and weight limits before finalizing a lighting design, since redesigning a plot after the fact, once a load chart comes back lower than expected, costs more time than starting with the real numbers.
Execution priorities
- Available rigging points and their weight limits at the confirmed venue.
- Whether overhead rigging is certified-rigger jurisdiction or open labor at that specific hall.
- Ground-supported alternatives for a venue where overhead rigging is not available or not worth the cost.
- Power circuits available for the lighting plot without overloading the booth's electrical drop.
Starting from the load chart
Every venue with rigging capability publishes, or can provide on request, a load chart showing available points and their weight limits. That chart is the actual constraint on a lighting design, more than the creative brief is, because a fixture plan the structure cannot support is not a usable plan.
We request that chart as part of venue confirmation, before a lighting designer finalizes a plot, so revisions happen on paper instead of after equipment is already reserved.
Rigging labor and who is cleared to climb
At the LA Convention Center and comparable union halls, rigging above a certain height is usually restricted to certified riggers under the venue's own jurisdiction rules, separate from the general I&D crew handling the rest of the booth build.
That labor gets scheduled as its own line item with its own call time, since rigging typically has to happen and be inspected before the rest of the install can safely proceed underneath it.
An inspection sign-off, not only a completed hang, is usually what clears the floor beneath a rigged point for the rest of the crew to work, so that step is built into the schedule rather than assumed to be instant.
When ground support beats overhead rigging
Not every venue or every booth benefits from overhead rigging. A hotel meeting room with a low ceiling, or a booth with a modest lighting need, is often better served by ground-supported trussing or simple stand-mounted fixtures, which avoids rigging labor and inspection costs entirely.
We weigh that against the creative goal early, since chasing an overhead look at a venue that cannot support it cheaply is often a worse outcome than a well-executed ground-supported plan.
A hotel property like the Fairmont Miramar is a common case for this tradeoff, where ground-supported lighting reaches the same visual result as a rigged plot would at a fraction of the setup complexity.
Power for the lighting plot
A lighting design that exceeds the booth's assigned power circuit either trips breakers on the show floor or forces an expensive additional power order from the general contractor mid-show, neither of which is a good outcome. We size the plot against the confirmed power drop before fixtures are ordered.
For a Barker Hangar or larger production, power planning also has to account for what else is drawing from the same circuit, since a shared drop with AV and other lighting can exceed capacity even when each element alone looks fine.
Lighting and rigging questions
Do all venues allow overhead rigging?
No. Availability and weight limits depend on the building's structure, so we confirm the load chart before designing around overhead points.
Who is allowed to rig fixtures at a union hall?
Typically certified riggers under the venue's own jurisdiction, scheduled separately from general exhibit install labor.
Is ground support cheaper than overhead rigging?
Usually, since it avoids rigging labor and inspection costs, and it is often the better choice for a modest lighting need or a low-ceiling room.
How do you avoid overloading the booth's power circuit?
We size the lighting plot against the confirmed power drop and account for what else, AV equipment especially, is sharing that same circuit.
Does an outdoor Santa Monica activation change the rigging plan?
Yes. An outdoor structure, a truss tower or a temporary frame, has to be engineered for wind rather than relying on a building's fixed rigging points, which is a different planning process than an indoor hall or hangar.
